NGC 7380

NGC7380 is an open star cluster that was discovered by Caroline Herschel in 1787. The rich nebulosity surrounding the cluster was not appreciated until the advent of astrophotography, and in 1959 it was included in the Sharpless catalogue of H-II regions (emission nebulae featuring the strong Hydrogen-alpha spectral line) with the designation SH2-142.
It is about 7200 light-years distant in Cepheus, the part of the region shown in this image being about 55 light-years from top to bottom.

As this is a narrowband image and our eyes do not see in narrowband, there is really no 'correct' way to display the colours, so image processors are free to map these wavelengths to the RGB channels our eyes see as they wish. In this case the three filters used pass photons from ionized sulphur (S-II), hydrogen (H-alpha) and oxygen (O-III) and I have mapped these to the RGB channels respectively.

As the H-α signal is dominant some adjustments to the channel strengths have been made to allow the other wavelengths to be seen. I have also tweaked the hues to achieve a more æsthetically pleasing result.In terms of the physics going on here, radiation from the hot young stars of the cluster is causing the edges of the dark clouds to glow as the stellar winds create bubbles of clear space around the stars.

NGC 7380 has been named the Wizard Nebula and in this orientation a little imagination reveals a figure sitting upright, looking toward the right, wearing a pointed hat and a cloak. His hands are outstretched as he seems to cast a powerful spell. He has a pointed nose and a bright blue eye, and looks rather angry.

North is toward the bottom right in this image.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
